Awesome. Thanks so much. I'll give it try.

Yes, I think you’re right. I haven’t been able to check the machine again yet since it’s not mine – I’m just trying to help out a friend – but it probably does have a brake, considering the previous controller was only 2.5 axes.
Now, what I’d like to ask for some advice on: if I want to keep the option of adding more expansions in the future and also a control pendant, would the 7i74 be a good choice? I see that it’s mentioned as a supported configuration in the 6i25 manual, so it seems like it could give me more I/O and flexibility.

I am putting together a complete,new, backup computer for my machine. (after a lightning storm took out my previous computer.)

I downloaded Linux-2.7.14 wheezy.iso  and used rufus.ie to make a usb image.
The new computer won't go past the boot screen. I fiddled around with the boot order etc but still no go.

I downloaded the latest version Debian 12 bookworm preempt-rt iso, made a usb image, and it starts right up to the install screen.

Is there something I need to do to make the older version start? I don't want to upgrade to the current version.because I would have to change a lot of things in my configuration.

I am running my previous backup computer currently. I suppose that I could clone the hard drive , or something like that.

"Wow, thanks for the super fast reply.The support from the Mesa team has always been top-notch. It's really impressive how you guys are always there to help.

Thank you so much for the detailed information. Your support, as always, is invaluable. This helps me a lot.

Thanks again!"

Hi, I’m working on wiring issues with an Orion PD200 CNC lathe. Could someone please share or upload the wiring diagram of the machine? It would be very helpful. Many thanks.

To set the PID for the spindle speed, I had to set FF0 before setting P and I, otherwise it would go straight to maximum speed.
So, I started the same process, I reassessed everything, except for trying to set FF0 to 0 and only play with P and I.
I just did it, and ohhhh!!! It moves and stops (only for small angular movements, about 10 degrees, and it's not always reproducible). Above that, it's unstable and starts spinning at full speed.

Well, first of all, it's not a hardware problem, the hal seems to be working, I need to look at the PID values ​​again.

By being so obsessed with it, you end up losing sight of the basic elements... thanks for putting this back on track...

your orient pid params in ini file, their values is 0, why?
you need to gradually debug these values.
all are 0 it's wrong. At least P and D have non-zero values.

mux2_orient.out always remains at zero (-0.01397) and doesn't move.
And orient.poserr decreases

The attached halscope (in halshow, I can't display orient.poserr)

 

It maybeif your user is cnc.


If that is not the case this may help

Or you may have to search for "linux forgot password"

The required kinematic component can be found here:
github.com/LinuxCNC/linuxcnc/blob/master...ts/xyzbca_trsrn.comp

debug with halshow.

disable the spindle's motor,
run M19, then see if <mux2_orient.out> become less when u rotate the spindle manually to the right angle. the pin <orient.poserr> can tell u that if ur direction is right.

the expected result is: <mux2_orient.out> follows <orient.poserr> both become less, utill <orient.is-oriented> become true, so <mux2_orient.out> will be 0, means M19 is done, spindle could stop now.
if the pins work as expected, the problem maybe in pid component.

btw, i haven't configured a spindle orienting hal code with frequency converter, i use a servo spindle, orient in csp mode. it works nice and could lock at the angle after orienting.

Probably not the issue, but you should have these lines as the bottom-most addf linesThe addfs are executed in some order and these lines should be the last.

Hi, 
I have not used my CNC milling machine for some time and have forgotten the password to start LinuxCNC. Can someone give me some help in resetting the root password, please?

Hello,

I would like to be able to orient the spindle in position.

The spindle encoder is a 1024-line encoder connected to an EL5101.

I've already set up a PID to control the spindle speed. The settings could still be improved, but for now it works and is acceptable.

However, for now, I can't get the spindle orientation to work. I'm not proficient enough with HAL to see where the problem might be.
If I start an M19 R10, for example, the spindle starts spinning and never stops. I've changed the PID values, but to no avail.
I have the impression I have an index problem, and I can't see it in the HALscope.

I'll send you the HAL and INI files, in case any of you experts spot a bug...

   

Thank you in advance for your help.
